Finding dream guide?

So I have been struggling on lucids this summer, and I had the task of finding my dream guide once I got one.

I finally got one the other night, and I tried to meet my dream guide, but I had an odd encounter that only confused me as to whether I actually met my guide or not.

I found myself in a water amusement park. I decided I wanted to try to 'summon' my dream guide, so I went to the top of a slide and climbed a wooden pole above it. I stood on top of a wooden platform up there and looked down on the water. I lifted my arms with my palms towards the sky and a giant face began to emerge from the water. It finally emerged completely and I was staring at a middle aged man's face. It was rough with glasses and grayish/brown hair. And for some reason, I somehow knew his name was Roger. I just felt a strong feeling that he was Roger.

This didn't last long, however. I soon woke up.

Could this be my dream guide?
Can anyone give me advice on how to actually find my dream guide or to assure myself that this was it?

Could very well be your DG. My DG put me through a test before I could find her. Each DGs introduce themselves in different ways. Then again, there are inpersenators out there. There's a red headed DC that claims to be my DG But I know she isn't, she doesn't have the same feel as the other one. Anyway, you know your DG when you see it/him/her. If he's in another dream, ask him if he's your DG.
